APPARATUS FOR BREWING TEA, COFFEE, AND OTHER- BEVERAGES.

Specification of Letters Patent.

Patented Apr. 23, 1912.

Application filed December 13, 1911. SeriafNo. 665,459.

To all whom it may concern Be it known that I, THOMAS JOSEPH How- LETT,a subject of the King of Great Britain, residing in city, county, andState of New York, have invented certain new and useful Improvements inApparatus for Brewing Tea, Coffee, and other Beverages, of which thefollowing is a full, clear, and exact description.

My invention relates to an improved apparatus for brewing tea, coffeeand other beverages.

In the drawings I have shown an apparatus best adapted for makingcoffee, and I shallproceed to describe the invention as applied thereto.

The main object, broadly speaking, is to provide an effective means forthoroughly extracting the juices of the entire amount of coffee used inthe apparatus.

In the drawings, Figure 1 is a vertical section of the entire apparatusin one of its preferred forms. Fig. 2 is a similar view showing theparts in a different position. Fig. 3 is a relatively enlarged sideelevation of certain details. Fig. 4. is a perspective view of certainparts.

1 represents an outer casing.

2 represents an inner casing mounted in the outer casing. The spacebetween the casings l and 2 is designed to hold water heated to theproper temperature to maintain heat in the contents of the inner casing2.

3 is a draw-off faucet connected by a pipe to the inner casing 2 whichcontains the beverage.

4: is a top cover for the outer casing 1 to close the same.

5 is a shoulder or flange at the upper edge of the inner casing 2located below the upper edge of the outer casing.

6 is a combined bag support and inner cover arranged to be supportedupon the flange 2. This cover 6 is separate from the top cover 4.

7 is a bag which is usually formed of suitable porous fabric and isdesigned to contain the coffee to be used in making the beverage. Thisbag is preferably supported by a collapsible ring 8 which may be sprunginto an annular space above the shoulder 9 on the lower side of thecover 6. The top of the cover 6 is open at one point to admit hot Water.10 is a shield for said opening.

In an apparatus, such as shown in the drawings, a suitable hot waterinlet pipe is customarily provided at the side of the outer casing l toinject water into the bag containing the coffee. Such a hot water supplypipe is so well known as to require no illustration or furtherdescription.

I also provide a combined coffee agitator and lifting device for the bag7, one simple form of which is illustrated in the drawings, in which'l212 represent the side arms of a stirrup-like device arranged to standunder the lower end of the bag 7.

1t1t are two lift rods hinged to the side members of the stirrup-likedevice and passing up through small openings in the top of the innercover 6.

l515 are handles at the upper ends of the lift rods 1%14.

When the bag 7 has been filled to the proper degree with a sufficientamount of coffee, it is placed bodily with the cover 6 into the positionshown in Fig. 1. Hot water is then admitted and allowed to absorb thejuices of the cofl ee within the bag 7. Since said bag usually holds aconsiderable quantity, I have found that much more satisfactory resultscan be obtained by agitating the coffee while the process of absorptionis going on. To do this without loss, I remove only the top cover 4 andby moving the rods ld-lt up and down several times, the coffee withinthe bag 7 will be agitated to such an extent as to thoroughly stir it upand permit the hot water to reach every particle. When the coffee isfinally completed and the juice is fully extracted from the coffee bean,it is desirable that the then useless bean be lifted from the beverage.To that end the lift rods are pulled up through the inner cover 6 untilsaid lift rods may be turned over into the position shown in Fig. 2,wherein they will serve to hold the combined agitator and lifter in anelevated position, as shown in Fig. 2. During this entire process, itwill be observed that the aroma of the coffee is not permitted to escapeby reason of the presence of the inner cover 6 which stands over theinner beverage receptacle or casing 2.

The ring 8 may be easily formed from a strip of wire bent into circularform of appropriate size for the edge of the bag 7 at the mouth or openend. This edge of the bag may be sewed to said ring. Since the ends ofthe ring are not united, said ring may be collapsed sufiiciently toinsert it (with the upper edge of the bag) in the space above thesupporting shoulder 9 at the lower side of the inner cover 6. In thisway a fresh bag may be substituted as often as desired.

What I claim is: 1

1. In an apparatus of the character described, a liquid receptaclehaving a discharge outlet near its lower end, a cover for saidreceptacle, a porous bag and means for connecting the same to saidcover, and a combined agitator and lifting device, part of said agitatorextending up through said cover whereby the contents of the bag may beagitated without removing the cover, said cover being apertured topermit of the passage therethrough of part of said agitator.
